I have no comment for taichi & microcurrent. But as for acupuncture, yes i do.

For me, I have tried acupuncture before and after ETS.
Pre-ETS: after a few treatments, I see no reduction on sweaty palms, so I decided to give up on acupuncture.

I don't wanna nag my loong story again......eventually, I went for ETS surgery.

After that, I found my sweating pattern very weird (at that time still do not know anything regarding CS/RS.). And so, i went for acupuncture again, trying to stop my CS/RS which is impossible. Now, you may ask me why I'm so sure that its impossible. Well,here i will roughly describe how the treatment goes......

They actually used 4 needles. 2 for wrist (area where you spray some colonge or perfume to test the fragrance) , 2 for feet (area where you try to kick a soccer ball on the grass with). Needles were then each poked into the nerves(I supposed it should have some connection with the sympathetic nerve). After that, they will have sort of power supplier(low current and using batteries) connected to those needles, and started to supply current to the needles. (I suppose this method of treatment should be roughly the same as a equipment named as "drionic", both supplying low electric current to "shock" or "stop" the nerves from hyperactiveness).

Therefore, there are no possibilty of seeing any effect if you have already cut or severed the connection between hands and body (which is normally nerves area at the armpits).

Post-ETS: I have actually went to them again and heard from those chinese physicians that this process must be done quite consistently (est:1-2years for light cases and 4years or more for more serious cases) in order to see the effect.

BUT to me, Its of no use anymore no matter how consistent I am.
